I'll post some pics when I next take the engine down to check thrust and see how the internals are fairing.

I aimed for as reliable a set-up as possible and after 100+ cycles the Fadec autostart ecu has not missed one start, light-up is instantanious every time. As a precaution max rpm was detuned by 10krpm and acceleration/deceleration times increased a little for flight assesment. I'll give it a few more hours flight time, then pending all still being OK mechanically I'll up the max rpm and shorten the accel/decel times and see what it is really capable of.

I'll also try to get a few more objective pilot opinions of the airborne performance in the meantime.

Parts build for the larger engine is now coming together, here's the shaft compared with an MW54 size ! Now I will just need something big to fly it in [>:]
